maps

I want to make a snapshot of a particular location from the map by calling intent or from a mapview.Can anyone help me.I am not getting the snapshot. Try this post, I believe this should help. It involves enabling the drawing cache and forcing it use that cache. Usually works on all views. Should work on MapView aswell Code from the link private Bitmap getMapImage() { /* Position map for output */ MapController mc = mapView.getController(); mc.setCenter(SOME_POINT); mc.setZoom(16); /* Capture drawing cache as bitmap */ mapView.setDrawingCacheEnabled(true); Bitmap bmp = Bitmap.createBitmap

Suggest any method to sort a multimap for both key and its values. For example- Input- (5,1), (1,9), (1,1), (5,2), (1,2) And the Output must be- (1,1), (1,2), (1,9), (5,1), (5,2). The answer is emplace_hint. Pseudo code will look like that:- insert_with_hint(M mmap, K key, V Value) { auto i1 = mmap.equal_range(Key); for (auto i2 = i1.first; i2 != i1.second; ++i2) { if (i2->second > Key) { // <-- Here add your sorting criteria mmap.emplace_hint(i2,Key,Value) return } } mmap.emplace(Key,Value) } You just need to copy all its elements to a multiset<pair<int, int>> : multimap<int, int> a; a.insert

Iterator iterator = map.entrySet().iterator(); while (iterator.hasNext()) { Map.Entry mapEntry = (Map.Entry) iterator.next(); System.out.println("The key is: " + mapEntry.getKey() + ",value is :" + mapEntry.getValue()); } This is my code. Now i don't want to use Iterator to get the values. Please help me to find best solution. Map<String, Object> map = .....;//Initialization here for (String key : map.keySet()) { // write your code here } //If you are just using keys of the Map for (Object value : map.values()) { // write your code here } //If you are just using values from your Map for (Map

I want to plot multiple maps using rworldmap, where each column is a separate month and the rows are years. I know this can be done in ggmap using facet_grid. How can I do this using rworldmap? For example, the mydata file contains columns for the latitude , longitude , month and year of each point. My code so far: library(rworldmap) newmap <- getMap(resolution = "high") plot(newmap, xlim = c(110, 155), ylim = c(-35, -20), asp = 1) p1 <- read.csv("mydata.csv") points(p1$lon, p1$lat, col = "red", cex = .5) To plot multiple maps using rworldmap, you could use layout and a couple of loops to

The next image was taken from www.Trimaps.com (I hope it's allowed to use images here, if not, please tell me and i'll remove it immediately). These images explain perfectly what i'm trying to accomplish. I have all the data one would need: Latitude/Longitude (in decimal values) of 4 corners of the desired area (from Google Maps). A beautiful custom image of a mountain (similar to the right image). All i need is the math. I've tried all the formula's, scaling/ transfomations, you name it. I'm sure it's possible as it depends on pure MATH, relatively simple math equations. www.Trimaps.com
